My 1998 DTR Project

[ricky0115]

I have never done any mechanical work to a motorcycle before, I’ve had 3 bikes since doing my CBT this year ha! First was a DT 125 RE and that’s where I fell in love with DTs! I made a silly mistake and swapped it for a WR125X & £500 because I wanted a supermoto. Learnt my lesson and picked up a cheap non runner DTR, however I haven’t photographed every part of the rebuild which I regret I have started taking a few. The build is far from complete having a baby on the way my budget is very tight.

Pretty much how it looked when I first got it, like some 12 year old got excited on need for speed sticking decals on. By this point I had put on some HEL brake lines, red ones to keep the colour scheme

Realised the frame had been painted with hammerite smooth so I stripped it to get the frame painted properly.

Must of been run to the ground, just look at that piston! Wish I took pics of the head gasket melted to the head.

Completely stripped

So after this I have no more pics until today when I began to put on my YZF-R125 wheels, since the last photo all stickers where removed(kind of) frame swing arm & forks were powder coated, fitted a new engine with a skimmed head and 5mm oversized wossner piston with the power valve pinned open.

Here she is starting to look somewhat decent.

& a new headlight.

Thanks for all your help along the way & I shall update as I progress!

Looking sweet bud.

Yeah no don't get a wr lol.

Wheels suit the bike, just need to get the work fabricated.

I was the same, bought a set of wheels and literally had no clue how to get them fitted.

[ricky0115]

Thanks!

Yeah the WR was awful lol.

I have ran into a problem with the rear wheel though, the dt spindle is too thick but the YZF spindle isn’t long enough. Should I get the dt spindle machined down or extend the YZF spindle? Not sure how I’d got about either to be honest!

Would like to fit a seat from an dt re or dtx and get rid of that hideous red thing though

[Calum]

@ricky0115 I'd just swap the bearings out mate. Use a bearing where the internal diameter is that of the dt spindle personally.

Leave the seat as is, just recover it.

[ricky0115]

@calum is that custom made bearings? Or would there be a possibility of putting dt bearings in there?

I actually have an original seat cover

@ricky0115 Hopefully off the shelf.

Sounds like you're going to need some basic engineering tools bud.

You're going to want to get yourself a Vernier Caliper

You want to get some off the shelf bearings mate. Because bearings will fail and you don't want it to be a pain in the back side.

If you can't get the bearings you want off the shelf, then the next logical step would be to get bearings suited to the external diameter of the spindle.

You might be able to machine the wheel hub to accept a larger bearing, but be wary not to go too thin.

Probably preferrably I'd have a spigot ring made up to press fit into the hub, reducing the size, and therefore not weakening the integrity of the wheel.

The Spigot ring would take up the slack from the undersized bearing.

simplybearings.co.uk has your back for all your bearing needs.

[ricky0115]

@calum thank you I will take a look tomorrow!!

[ricky0115]

@calum had a micrometer in my tool box not a fancy LCD one though! Simplybearings has the ones in need 20x35x11 so now all I need is the spacer between the bearings? Guessing I will have to get it made up along with the outer spacers or machine down the DT spacer?

Thanks

[Calum]

@ricky0115 I'd make it up from fresh. To turn down a piece of ally, is going to be like literally £10 and worth doing.

I will leave the measuring up to you, but remember, to measure, measure and measure again. Don't leave anything to chance.

[ricky0115]

@calum thanks very much!

Decided to change the seat cover this afternoon before work, also reshaped it so it fits the MX fender more natural & installed my trail tech in my bar pad.

Not sure if I like the cut plastic on the back

How’s my shaping?

Trailtech vapor, not sure how to overcome the crinkle of the pad tape
